Question

在我的项目之前，我使用了Google plus授权，但是现在我想用玩游戏登录方法代替它。我在Firebase文档中找到了有关此信息。但是，在阅读了这些信息之后，我没发现什么。

1）如何处理从启动Intent返回的结果？之前我使用下面的代码来处理google plus结果：

if (requestCode == RC_GOOGLE_SIGN_IN) {
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            // Google Sign In was successful, authenticate with Firebase
            GoogleSignInAccount account = task.getResult(ApiException.class);
            firebaseAuthWithGoogle(account);
        } catch (ApiException e) {
            // Google Sign In failed, update UI appropriately
            Log.w(TAG, "Google Sign in failed", e);
            updateUI(null);
        }
}

2）如何启动它？我将以下代码用于google plus授权：

// Configure Google Sign In
GoogleSignInOptions gso = new     GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
        .requestIdToken(getString(R.string.default_web_client_id))
        .requestEmail()
        .build();

mGoogleSignInClient = GoogleSignIn.getClient(mActivity, gso);

// This method called when user push google sign in button
private void googleSignIn() {
    Intent signInIntent = mGoogleSignInClient.getSignInIntent();
    startActivityForResult(signInIntent, RC_GOOGLE_SIGN_IN);
}

3）如何注销？我想这段代码与玩游戏是一样的。

// Firebase sign out
mAuth.signOut();

// Google sign out
mGoogleSignInClient.signOut().addOnCompleteListener(mActivity,
       task -> updateUI(null));

我的firebaseAuthWithPlayGames方法，我需要从OnactivityResult调用该方法：

private void firebaseAuthWithPlayGames(GoogleSignInAccount acct) {
    Log.d(TAG, "firebaseAuthWithPlayGames:" + acct.getId());
    String authCode = acct.getServerAuthCode();
    if (null == authCode) {
        String errorMsg = "firebaseAuthWithPlayGames: authCodeNull - Failure";
        Log.d(TAG, errorMsg);
        showToast(errorMsg);
        return;
    }
    showProgressDialog();

    AuthCredential credential = PlayGamesAuthProvider.getCredential(authCode);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(mActivity, task -> {
                if (task.isSuccessful()) {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d(TAG, "signInWithCredential:success");
                    FirebaseUser user = mAuth.getCurrentUser();
                    updateUI(user);
                } else {
                    // If sign in fails, display a message to the user.
                    Log.w(TAG, "signInWithCredential:failure", task.getException());
                    showToast("Authentication failed.");
                    updateUI(null);
                }

                hideProgressDialog();
            });
}

您知道使用此授权方法的任何示例吗？我看了官方的auth示例，但是没有玩游戏的授权。

在哪里可以看到使用playbase firebase auth的示例？
